Alloy 825ndiyo Iyo yakakwira nickel yemukati inopa iyo alloy inoshanda kushushikana ngura kupwanya kuramba.Corrosion resistance yakanakira mumhando dzakasiyana dze media, senge sulfuric, phosphoric, nitric uye organic acids, alkali simbi senge sodium hydroxide, potassium hydroxide uye hydrochloric acid mhinduro.
Kushanda kwepamusoro kweIncoloy 825 kunoratidzwa munyukireya inopisa inonyungudika ine zvakasiyana-siyana zvinopisa media, senge sulfuric acid, nitric acid uye sodium hydroxide, zvese zvakagadziriswa mumidziyo yakafanana.
